Question

Into a circular drum of radius 4:2 and height 3.5m,how many full bags of wheat can be emptied if the space requrired for wheat in each bag is 2.1m^3(take pie=3.14)

Answer 1

Given, r = 4.2m,

h = 3.5m

Volume of the drum = (πr2h)m3 = 3.14x(4.2)2x3.5

Volume of each bag of wheat = 2.1 cubic metre

Number of bags = Volume of drum

Volume of a bag = 3.14x4.2x4.2x3.5

2.1 ≈ 92 bags

Answer 2

Given, r = 4.2m,

h = 3.5m

Volume of the drum = (πr2h)m3 = 3.14x(4.2)2x3.5

Volume of each bag of wheat = 2.1 cubic metre

Number of bags = Volume of drum

Volume of a bag = 3.14x4.2x4.2x3.5

2.1 ≈ 92 bags
